Simplex negative right hand side

WebbThe simplex method is a general-purpose linear-programming algorithm widely used to solve large scale problems. Although it lacks the intuitive appeal of the graphical approach, its ability to handle problems with more than two decision variables makes it extremely valuable for solving problems often encountered in production/operations management. http://ecoursesonline.iasri.res.in/mod/page/view.php?id=2928
